The number 827 has got 2 factors, that are capable of dividing the number completely without leaving any remainder. Thus the number 827 is a prime number. The factors of 827 include 1 and 827.
A number to be a prime number should follow the criteria, which is that it should not have factors more than 2. Here, 827 has only 2 factors, hence making it a prime number.
Given below are a few ways that can be used to find prime or composite numbers.
The different methods we can use to check if a number is a prime number are explained below.
For the counting divisors method, it is to be checked whether the number is divisible by any numbers other than 1 and the number itself.
The counting divisors method for 827 would simply be
Divisors of 827 = 1, 827
Number of divisors = 2
The number 827 can be considered prime.
In the division method, we try to divide the number by any of the prime numbers. If we cannot, then it is considered a prime number.
In the divisibility method, the prime number only has 2 divisors, which are 1 and itself.
The divisors of 827 are 1 and 827.
Thus, 827 consists of only 2 factors, making it a prime number.

827 is present in the list, it is a prime number.
Prime Number: A natural number greater than 1 that has only two distinct positive divisors: 1 and itself. For example, 827 is a prime number because its only factors are 1 and 827.
Divisors: Numbers that divide another number exactly without leaving a remainder. For 827, the divisors are 1 and 827.
Divisibility Test: A method used to determine whether a number is divisible by another number. If a number can be divided evenly by a divisor, then it is divisible by that number.
Prime Number Chart: A list of all prime numbers up to a specific value. It is a helpful tool for quickly identifying whether a number is prime. For example, 827 appears in the list of prime numbers under 1000.
Counting Divisors Method: A method where we count how many divisors a number has. If a number has exactly two divisors, it is prime. In the case of 827, the number of divisors is 2, confirming it is a prime number.
